Description copied from class: IntegratedFunctionCompiler
Generate Java code to evaluate the expression as a SequenceIterator

Specified by:
compile in class IntegratedFunctionCompiler
Parameters:
compiler - the compiler service
expr - the integrated function call to be compiled
arguments - the arguments supplied to the function call
variables - an array of strings each being the Java name of a variable that holds the value of the corresponding argument, either as a SequenceIterator in the case of an argument that allows more than one value, or as an Item if the argument only allows a singleton
Returns:
a simple Java expression (usually the name of a variable that has been declared). If the result type of the function is boolean, this variable will hold a Java boolean. If the result type is an optional item, it will hold an Item (using null to represent an empty sequence). If it is any other type, the variable will hold a SequenceIterator, In each case the Java variable will at run-time hold the value of the XPath expression
